The split-type utility pole band 10 is applied so that the pair of band members is wound around the peripheral surface of the utility pole, and is fixed by tightening bolts 11 and nuts 12, which is the same as that generally used in the past.

A lead screw mechanism is provided between the utility pole, the end face 3B of the box-shaped support member 3, and the barrier 5. That is, a lead screw 14 in which a nut 13 is screwed is disposed between the end face 3B and the barrier 5, and both ends of the lead screw 14 are rotatably supported by the end face 3B and the barrier 5. The lead screw 14 uses a headed bolt, and a pin 16 is inserted sideways into the nut 15 and the lead screw 14 fitted at the tip of the screw 14 so that the lead screw 14
Is kept from falling out.

A leg piece 18 extending from a washer 17 integral with the nut 13 is slidably fitted into a hole 19 in the end face 3B of the box-shaped support member 3, and the leg piece
The length of the leg 18 is set to such a size that the leg piece 18 does not come out of the hole 19 even when the nut 13 comes closest to the barrier 5 by rotating the lead screw 14.

Therefore, when the lead screw 14 is rotated, the nut 13 advances and retreats on the lead screw 14 without rotating with respect to the box-shaped support member 3.

A pair of left and right convex portions 20 protrude from the washer portion 17 in a direction opposite to the leg pieces 18, and a hole 21 or a concave portion for receiving the convex portion 20 when the nut 13 approaches the barrier 5 is provided in the barrier 5. I have.

Then, at the center of the end face 2A of the box-shaped locking member 2 on the transformer side,
A downwardly facing slit 22 is provided in the lead screw 14 so as to straddle it. Holes 23 are formed on both sides of the downward slit 22 so that a pair of right and left convex portions 20 protruding from the washer portion 17 of the nut 13 penetrate.

The depth of the downward slit 22 and the height position of the hole 23 are determined by hooking the box-shaped locking member 2 on the upward slit 4 of the box-shaped support member 3 so that the lower side of the end surface 2A of the box-shaped locking member 2 With the bottom of the upward slit 4, the lead screw 14 is received at the innermost part of the slit 22, and the hole 23 is set so as to match the hole 21 of the barrier 5.

The convex portion 20 of the nut 13 and the hole 21 of the barrier 5 are relative to each other, and a convex portion may be provided on the barrier 5 side, and a concave portion may be provided on the nut side. The shape of the projection and the hole or the recess are not limited, since they only have to engage with each other.

The box-shaped locking member 2 is hooked on the upward slit 4 of the box-shaped support member 3 in a state where the nut 13 is returned to the end face 3A side by turning the lead screw 14, and the end face 2A of the box-shaped locking member 2 faces downward. The slit 22 straddles the lead screw 14 and the hole 23 on the end face 2A of the box-shaped locking member 2 and the hole 21 of the barrier 5 of the box-shaped support member 3 face each other.

Next, when the lead screw 14 is turned in the opposite direction to the front, the nut 13 moves toward the barrier 5, and the projection 20 of the nut 13 passes through the hole 23 of the end face 2 A of the box-shaped locking member 2, and the hole 21 of the barrier 5 At the same time, the end surface 2A of the box-shaped locking member 2 is sandwiched and fixed between the nut 13 and the barrier 5.
